Common Things in All Acids and Bases:-

All acids have H+ ios in common

All bases have OH- ions in common

 Acids produce H+ ions which  ar responsible for their acidic properties.

Acids solution in water conducts electricity.

An Acid or a Base in water solution:-

  • Acids produce H+Ions in presence of water.
  • H+ ions cannot exist alone , they exist as H3O+ ions.

H+   +   H2O      H3O+

HCl  +  H2O     H3O+ +  Cl-

Bases when dissolved in water gives  Oh-  ions.

For Example:- 

 

Bases soluble in water are called alkali.

 It is recommended that the acid / base should be added to water and not water. Is added to acid/ base, the heat generated may cause the mixture to splash out and cause burns and the glass

conatiner may also break due to exessing  heating.

  Mixing an acid or base with water results in decrease of concentration of ions per unit volume. Such a process is called dilution.
